Implement queue producers and consumers using Vercel Queues docs and SDK contracts.

Step 1: Classify the request

Choose one path before writing code:

Request type	Primary reference
First-time setup, minimal producer + consumer	`references/quickstart.md`
SDK usage, options, retries, transport behavior	`references/sdk.md`
API-level integration (custom clients, non-SDK consumers)	`references/api.md`
Delivery semantics and architecture decisions	`references/concepts.md`
Polling workers and mixed push/poll design	`references/poll-mode.md`
Local setup and debugging	`references/local-dev.md`

If the task spans multiple categories, read only the relevant files above.
